    HFCS, Sucrose Don't Increase Liver Fat Under 'Real World' Conditions

    Study examined 64 people who consumed low-fat milk sweetened with either HFCS or sucrose

    A recent study published in the Journal of Applied Physiology, Nutrition and Metabolism finds that the consumption of both high-fructose corn syrup (HFCS) and sucrose (table sugar) at levels consistent with average daily consumption do not increase liver fat in humans, a leading cause of non-alcoholic fatty liver disease (NAFLD). The study is the latest in a series of scientific reports that find HFCS and table sugar as being metabolically equivalent.
     
    Increased fat levels in the liver and muscle tissue have also shown to contribute to insulin resistance, a key factor in the development of type 2 diabetes.
     
    The study, conducted by James Rippe, founder and director of the Rippe Lifestyle Institute and professor of biomedical sciences at the University of Central Florida, examined 64 people who consumed low-fat milk sweetened with either HFCS or sucrose with the added sugar matching the 25th, 50th and 90th percentile population consumption levels of fructose, for 10 weeks.
     
    The results showed fat content of the liver remained unchanged when the six HFCS and sucrose groups were averaged. Fat content in muscle tissue was also unchanged over the 10 weeks when the six HFCS and sucrose groups were averaged.
     
    "The study's results are compelling because this is the first study of its kind to test the effects of HFCS and sucrose on liver fat levels in humans using real world conditions," said Dr. Rippe, who received a grant from the Corn Refiners Association (CRA) to conduct the study. "Previous studies that sought to find a link between caloric sweeteners and diseases such as type 2 diabetes and liver disease often subjected individuals to unrealistically high levels of fructose or had subjects consume fructose independent of glucose, which is just not how fructose is consumed in our daily diet. Using real world conditions, we find that HFCS and other caloric sweeteners do not appear to increase liver fat or contribute to insulin resistance."
